The Juventus coach considers the Argentine forward, who resumed his level with the Vecchia Signora.
"Gonzalo is a great player who had a difficult season," Juve coach said about the former Napoli striker, who has only three goals in 11 games although his football production does not stop receiving praise.
Sarri said he saw the Argentine train in the preseason "with an exceptional level of motivation. In London, I had heard some comments from him that I had not liked at all, but now quite the opposite, which meant that something had changed in his mind ".
"When he has great motivation, he is a very important player," He insisted on the new version of the Argentine that is being seen in the last semester of the year.
